In the SI we use sieverts, grays, and becquerels. Before the SI came
into being and defined those units, folks used rems, rads, and curies.
Relationships:
1 rem = 0.01 Sv
1 rad = 0.01 Gy
1 Ci = 37 GBq
See Table 3 of the SI Brochure:

Dear Gene and Jim,
have only heard millisieverts here in all of the Australian media:
newspapers, radios, and TV. I have not heard or seen rems at all.
Which is correct SI use?
Cheers,

Pierre,
I heard rems on CNN, but no sieverts.
I also heard Anderson Cooper repeatedly speak *nothing but kilometers* for
distances on CNN, suggesting deliberate emphasis on metric distances.
Now if Anderson could only learn to pronounce km correctly, prefix name (kilo) followed
by unit name (meter), with out the "lom" slurs.
Gene.

I heard someone mention the figure 400 mSv/h on NPR in connection with the
nuclear reactor in Japan. Did anyone else give it in rems? Have you heard
other radiation units in reporting on the event?
